There are three stages in wastewater treatment, the first stage is called primary primary treatment. The only difference is that industrial treatment is more focused on removing chemicals, while the domestic process is more inclined to remove organic matter. While these types of wastewater treatment plant serve to treat different types of sewage, the process of treatment is very similar at any given treatment plant. The main difference between domestic and industrial treatment plants is industrial treatment is done on site while domestic treatment plants treat sewage from a surrounding area. Wastewater treatment plants can be divided into two main kinds: industrial treatment and domestic treatment. This creates an aquatic environment completely deprived of oxygen called a dead zone, where little to nothing can live. This allows for large growths of algae called algal blooms that can greatly offset aquatic ecosystems.Īt first the algae produces excessive amounts of oxygen, but after the blooms inevitably die, microorganisms use up all the oxygen during decomposition. Nitrogen and phosphorous are the key ingredients in most industrial fertilizers, and therefore when they manage to get into water bodies through sewage they actually act as a surplus of nutrients for algae. These chemicals are important because they contribute to a very unique kind of pollution known as eutrophication or nutrient pollution. The most notable example of industrial sewage is that which comes from agriculture and other industries that contaminate their wastewater with nitrogen and phosphorus. These can range anywhere from ammonia as a byproduct of iron production to oil fracking bringing toxic substances from underground to the surface. Since there are many different kinds of manufacturing processes, the specifics of the pollution that’s caused from improper sewage disposal can vary greatly.ĭepending on what is being made and the process it involves, the type of waste that comes from industrial processes can change. Types of Wastewater Industrial WastewaterĪlmost all industries require water at some point in production, and in almost every industrial system water becomes contaminated with various pollutants.
The pollutants found in wastewater have detrimental impacts on human health and the environment. Sewage, or wastewater, is water that has been used in factories, homes, or other buildings and contains pollutants because of it.
